EXPEDITION 325 GREAT BARRIER REEF ENVIRONMENTAL CHANGES

This expedition collected cores from the fossil coral reefs on the seaward site of the Great Barrier Reef to establish the course of the sea-level rise during the last deglaciation, to define sea-surface temperature variations and to analyse the impact of these environmental changes on reef growth.

EXPEDITION 313 NEW JERSEY SHALLOW SHELF

The expedition collected cores from sediments deposited 14 to 24 million years ago, a time of considerable sea-level fluctuations due to climatic variations. This IODP expedition received additional financial support from the International Continental Scientific Drilling Program (ICDP).

EXPEDITION 310 TAHITI SEA LEVEL

This expedition investigates the drowned reefs and reef terraces around Tahiti to reconstruct the timing and magnitude of sea-level fluctuations and the evolution of climate conditions during the last deglaciation.

EXPEDITION 302 ARCTIC CORING

The Arctic Coring Expedition (ACEX) was the first IODP mission-specific platform operation managed by ESO (in cooperation with the Swedish Polar research Secretariat – SPRS). The drillsites were located on a submarine high, the Lomonosov Ridge, at a point only 250 km from the North Pole. ACEX was a huge logistical challenge because the drillship had to hold its position while surrounded by the moving ice sheets of the Arctic Ocean. This required two icebreakers, the Oden and Sovetskiy Soyuz to clear a channel through the ice to allow a third icebreaker, Vidar Viking, specially converted for the task, to undertake the drilling.
